Hello everyone!
So basically i bought the ASUS VG258QR about a month ago, everything was looking fine at first but then i found out that the monitor has ghosting, i tried setting TraceFree from 100 to 80 to 60-40-20-0 and well.. that didn't solve me the problem :\
ELMB is off but when i turn it on i get even much worse ghosting, like literally i barely move my mouse in-game and can see very noticeable ghosting everywhere.
Btw my monitor is plugged in to a GTX 960 and i run 165fps and above, also maked sure that i actually run 165Hz.
I don't know what to do anymore because i also can't return my monitor to the store for a refund anymore so, yeahh..
I am going to get a new gpu soon but god knows if it will solve the ghosting issue :\
Please guys i really need your help, i will much more than appreciate it!

This monitor will only work ok with G-Sync compatibility enabled and for that you need a new gpu.

Presets should not affect response time and I didn't notice Racing mode faster.
Racing mode has wrong sharpness and it's blocked so you can't change it, text won't be clear.
Also, things will have more blur. You can see this in ufo ghosting test.
